The Jordan Valley and the territories that dominate it shall be under Israeli sovereignty. The Jordan river will be the permanent eastern border of the State of Israel. The Kingdom of Jordan is a desirable partner in the permanent status arrangement between Israel and the Palestinians in matters that will be agreed upon.
